[petsc-dev] Unused macros in petscconf.h

[Smith, Barry F.]

https://bitbucket.org/petsc/petsc/pull-requests/1834/remove-testing-and-inserting-into/diff

removed about 1/3 of the entries for a build with about 10 external packages

perhaps there are a small number of entries that may still be removed but I think I got rid of most the unneeded ones.

Left pthread because I would like to use it soon :-)
